(A draft StackOverlow questioned that I answered for myself) Draft question I am using mongosh version 2.26 on iTerm2 (Build 3.5.0) on a Mac. I am starting to explore MongoDB with the aim of setting up a MERN website. When I run mongosh, the Mongo shell correctly opens. Within the Mongo shell, I switch to and create a new db, e.g. one called random, by > use random. $ show collections correctly shows no collection....

In this Write-the-Docs London talk on 2 May 2024, speakers shared their experiences with using software tools to automate the publication of their companies’ documentation. Because these software tools are also used by programmers for computer code, this approach is also known as “Doc-as-Code”. Vladimir Izmalkov gave the first presentation. He gave a broad overview of common software tools for Doc-as-Code, including (amongst others):- Git for version control Markdown for formatting text Hugo for deploying a static website Vladimir then shared VK Private Cloud’s experience with migrating documentation from Confluence to Git in a short time frame, and in the process changing the underlying document format from Microsoft Word to AsciiDoc....

1 American authors sometimes forget for many people the dream is to emigrate to somewhere like America. This is a very different kind of ambition from being “So Good They Can’t Ignore You”. 2 Do we have to be very “successful” in the first place? In the sense of being better by a significant than others on some objective measure? Surely not, even though that is the inevitable premise of self-help....

Demo: download button here for laptop and desktop Background There is an issue with Barrister Admission Bundle I have wanted to solve for some time. I wanted to make a website where users (pupil-barristers) could enter all required information at once, and then download a Word document. The Word document would have all the information in the right place. But it also needs to be modifiable (as users probably have their own style preferences)....

I fell in love with the technology of CSS recently, having obsessively followed a YouTuber (and CSS guru) called Kevin Powell. One of the articles that Kevin recommends is the Dao of Web Design. In essence, the article argues that web as a medium is fundamentally different from printed media because the layout of a webpage has to work on so many different devices: mobile phone, tablets, laptops, Desktops And also on different browswers with customisation such as dark reader or screen readers....

Kevin Powell points out that people (certainly me!) tend to be too impatient with CSS. They assume it is a “simple” technology and just resort to looking up answers on Google as they go along, without trying to understand the undelrying principles. But paradoxically in CSS more than in (say) Javascript, fundamentals matter even more. The layout of a web page differs from device to device and from browser to browser....

Quick test: what do these code snippets do? const a = new Promise(function (a) { a }) const b = new Promise(function (b) { b("success") }) const c = new Promise(function (a, b) { b("failure") }) const d = Promise.resolve("success") const e = Promise.reject("failure") const f = new Promise(function (a, b) { a("success") b("failure") }) const g = new Promise(function (a, b) { b("failure") a("success") }) const h = new Promise(function (a, b) { throw new Error() }) const i = new Promise(function (a, b) { a() }) const j = new Promise(function (a, b) { b() }) const k = (number) => { return new Promise(function (a, b) { a(number * 2) }) } Check by opening the console in your browser and test with e....

Ask Your Developer is Twilio co-founder Jeff Lawson’s advice to Businesses looking to survive and prosper in the digital age. In short, Jeff argues that: (1) Businesses need to embrace technology (esp. web technology) to compete; (2) Rather than buying them ready-made (e.g. from a consultancy), businesses do better by buying “software parts” and assemble a custom solution. For example, Twilio excels at providing tools for integrating mobile phone text-messaging to software programmes; Cloudfare specialises in protection from DDOS attacks....

I recently came across a situation where I was fetching information from a RESTful API. After some intermediate steps, I ended up with an array of objects, all of which have the same set of attribtues (e.g. including an id). I wanted to have a way of printing a list of ids of the objects, e.g. let attribute = id array.map(object => <li> object.attribute </li>) But this didn’t work. It took me a while before I realised what I needed is instead:...

Historical accident The answer seems to be historical accident, not intentional design. Back in the old days, Netscape advocated event capturing, while Microsoft promoted event bubbling. Both are part of the W3C Document Object Model Events standard (2000). – Arun P Johny If this is correct, the events of the browser wars in the 1990s are still shaping Javavscript into the 2020s! In a way, this is unsurprising: backwards compatibility is important, which means features are often in a way that seem inelegant in hindsight....
